A couple of new articles have crept out recently. The first is me pretending to understand DNS.
I used this configuration in place of the “/etc/hosts” in my VMware RAC installation and it worked great.
The second is a brief romp through edition-based redefinition.
This article started to get really big and feel like a rewrite of the manual, so I stripped most of it out and really just left a couple of examples of how it can be used. I figure this is enough to give you a feel for what it can do, but isn’t as daunting as working through the manuals if all you want is a quick taste.
I’ve seen edition-based redefinition described as a killer feature, but I’m not so sure myself. Don’t get me wrong, I think it is really cool, but “really cool” doesn’t always become “frequently used”. As I was playing with it I had flashbacks to Workspace Management introduced in 9i. I’ve spoken to a lot of poeple over the years and very few even remember it exists, let alone use it.
There is nothing conceptually difficult about edition-based redefintion, but there are potentially a lot of working parts involved and therefore a lot of scope for human error and/or confusion. I’m sure some people have been praying for something like this for a long time, and others will remain blissfully ignorant of it forever. It would be interesting to gaze into a crystal ball and see how much this stuff is used in a few years time (and get some lottery results).
